Global sea levels are expected to rise dramatically over the next 100 years, a scary prospect for residents of a city surrounded by water. But beyond signing up for swimming lessons, what can we do to prepare? The Commonwealth Club tackles that question tonight with Adapting to Sea Level Rise in the Bay Area. The panel of experts features the senior scientist at the San Francisco Estuary Institute Robin Grossinger, coastal geomorphologist Jeremy Lowe, and John Bourgeois of the State Coastal Conservancy. The discussion will focus on the natural ecology of the bay, and what changes are likely with rising sea levels. Special attention will be given to examining how the bay evolved during previous periods of sea level rise, and ways to create a more sustainable shoreline through natural processes and wetlands restoration. One talk won't solve all of our problems, but it sure beats learning the backstroke.
